He stopped.
The movement was so abrupt that he nearly stumbled, and after a beat, all six eyes opened. It might have been, for Haven, eerily silent for a few seconds, and then there was a rustle as the hound lurched back into motion. But he didn't step forward; instead, he was reaching for the dark metal pocketwatch hanging around his neck, on a tarnished chain.
He pulled this slowly over his head, a moment of inspiration driving him: and then, halberd leaned up against him, he carefully wound its little metal knob.
Tick. Tick. Tick. It sprang back into life, and he lifted this, and closed his eyes. He turned, moving it farther from him, closer, listening, focusing. And after a moment, he put it into his mouth, testing this: holding it in his jaws. Then back out again, dangling, comparing.
"This piece of time is a guide," he said softly, aloud, with the tone of one coming to a conclusion. Then he set off, taking the halberd in hand, the pocketwatch hanging before him in another. His steps were slow, but careful, and he didn't stumble in the sand.
Eventually--whether by chance, or by actual hearing--he came to a halt some feet from the wall. Then he reached out, feeling--and began to move closer, and farther, shifting the pocketwatch to and fro with its quietly-echoing ticks. It wasn't very easy to hear over the crashing breakers of the bay, or the cries of the gulls, but it was there, at least, and if he listened very closely he could hear it.
At last, soft-padded hands found worn rock, and he paused there, hand flat against stone, halberd again tucked under one arm.
The eyes opened, and he turned to look for Haven. "Crystals are owed," he said at last; "It will show him where to search."
